a more perfect union (ao3) - romanoff
bucky/steve/tony
E, 157k
Summary: Post ‘Civil War’, Tony is forced to make some very hard decisions. He’ll do what it takes to protect his own, even if Steve hasn’t been seen in months. He’ll do what he has to do to.

Summary: Tony Stark’s born an omega in a world where that means he’s supposed to follow certain social rules. He becomes Iron Man anyway: Fuck biology.
If only his biology (and the world) would quit fucking him back.

Summary: Bucky spots the leaflet under some old magazines as he eats. It’s crumpled and worn. He’s looked at it several times in the past seven months since he found it in the Omega center. It has pictures of smiling couples holding hands, sitting on picnic blankets under willow trees. They’re outlined by slogans like “Serve Your Country” and “Your Contribution is Needed”.
heat (ao3) - Ryoko21
clint/steve/tony
E, 95k
Summary: Clint was a badass. He was an assassin, a killer, a terrorist, and an archer. But he was also an omega. And as long as his organization kept control of the suppressants that kept him from going in to heat, he’d keep doing whatever they asked. No matter how distasteful he found it, or how little of his soul was left at the end.
But when Clint is injected with heat inducers, rendering his suppressants useless, can SHIELD’s top agents save the archer before he goes mad?
hurts to be human (ao3) - ABrighterDarkness

Summary: Bucky was…he wasn’t jealous not in any way that meant he resented what they had or would cause harm or problems to get what they had. But, it did paint a very pretty picture of what he had been missing while they had him. Would he have found this? Fallen into this sort of family dynamic had he not been taken? Could this have been his life?
Not that it really mattered, in the end. He had been taken. He had spent the last few years at the beck and call of a massive network of Omega-Traffickers. Bucky never had a potential buyer in the works. Not even a cursory look from one as far as he knew. Something for which he was undeniably grateful, but at the same time what he did have was falling under the unending control and manipulation. Forced to lie, cheat, and steal. Forced to harm others while under the force of the Commands. What he did have was memories; too many of them and too few of them good.
i’d give my soul (ao3) - WeebDa
bucky/steve/tony
M, 114k
Summary: “Always the same. Shit, what is it with you Alpha’s and your egos,” Tony’s mouth ran off with words he didn’t even think about saying.
“Tony. Don’t start,” Steve tried to calm down. His mind kept telling him not to let an omega to talk to him in such a way. He wanted to press Tony down, make him submit when only minutes ago he wanted to wrap himself around Tony.
“Look, I get it. He’s your best friend. But you have to stop being a self-pretentious idiot who thinks he could punch his way out a situation.”
“Like blasting your way out of a situation is much better?”
“Yes it is, because I fucking use my head. This is a fucking conspiracy. They probably waited to tell you about all this bullshit when they had you enraptured deep enough to their ‘cause.’ Why do you think I privatized my suit, what do you think SHIELD would do if they got their hands on it? Everything they do is for their own gain.”

Summary: Peter probably shouldn’t be falling asleep on Deadpool, but after the Merc with a Mouth saves him from being abducted by two dick Alphas, he doesn’t try as hard as he should to not.
i’m right on top of that, tony (ao3) - DyslexicSquirrel

Two heads turned toward him, Ms. Potts standing with a practiced, professional smile. “You must be Mr. Rogers. I didn’t realize the time.”
Stark looked from her to Steve and back, his eyes widening slightly. He got to his feet, shaking his head. “No, uh-uh, not happening, Pepper. Is he even old enough to work? If he says ‘I’m right on top of that, Rose,’ I’m jumping out the window.”
life is unfair (ao3) - Ladate
steve/tony
E, 84k
Summary: Tony is an asshole and Steve may be a little bit in denial. Tony is Alpha and Steve is, well, not really Alpha but that is a secret. This is a long suffering path from hate to love. In a world where gender defines your life, where biology controls your body, Steve is trying to figure out who he is and what he wants from life.
It was supposed to be funny but it turned out very angsty.
love without doubt (ao3) - Renai_chan

Summary: Tony is kidnapped and, months later, the rest of the Avengers are captured by the same people when they try to rescue him. When SHIELD gets them back, they’re forever changed and bonded.
need not be (ao3) - Chuchiwan
peter/wade
E, 111k
Summary: Peter presented as a rare male omega when he was seventeen but he’s not going to let that get in the way of being Spider-Man. His social life? Maybe.
He’s nearly twenty now and although his life as Peter Parker isn’t the most healthy (A.K.A he’s a hermit) Spider-Man is doing his job to protect the city.
Then a potentially dangerous alpha enters his life and everything seems to go wrong… but it might be worth it?
never easy, but always worth it (ao3) - GingerEnvy

Summary: The Avengers are a Pack, they’re good together, they fight and live and survive together, but suddenly Clint gets taken and everything shifts from then on out, and when he’s rescued things will never be the same for them.
nobody wants to be an omega (ao3) - LeafyGreenQueen773
peter/wade
E, 164k
Summary: After he was bitten by a radioactive spider, Peter Parker’s life was swept up in a whirlwind of high-tech suits, hectic fights, and rubbing elbows with New York’s finest heroes. At least he knew one thing: it was easier to be a Friendly Neighborhood Spider-Man as an independent Beta. But when his late presentation as an Omega nearly gets him killed, he has to face the truth: his life is anything but easy. Especially when the Alpha who gets to help him through his heats is the one and only Merc With A Mouth.
Scents and Sensibility: The Working Assassin's Guide to Supersoldier Seduction (ao3) - galwednesday, silentwalrus, skellerbvvt
steve/bucky
E, 93k
Summary: Captain America wakes up from the ice in 2013. The Winter Soldier wakes up in 2009, or rather defects from HYDRA, for a value of defect that’s closer to decimate. He ends up working for SHIELD. In April 2014, he’s assigned to Captain America’s mission as a sniper.
Steve’s just trying to get some kind of life together. Bucky is too, or at least he was until tall, blond and Captain shows up and starts just - being there, all the time. It’s terrible. It’s the worst. He has to do something about it.

Summary: They don’t love each other. They barely even like each other.
take my hand (and my whole life too) (ao3) - portraitofemmy, rainbow_marbles
steve/bucky, riley/sam
E, 56k
Summary: First and foremost this is a story about love. It’s about two people who, for different reasons of their own, have become comfortable with the idea of being alone. But when chance or fate (or the will of a stubborn little Alpha unwilling to let injustice stand) puts them in each other’s path, the courage to try to make a good thing work is easy to find.
This is a story about love. It’s story about partnership. It’s a story about the work you have to do, and how very worthwhile loving and being loved can be.
the last omega (ao3) - deadto27
steve/bucky
E, 102k
Summary: Bucky Barnes is the last eligible omega left in his town after Thanos takes out half of the world’s population. The government puts in place a mating program to find compatible alphas and omegas and bring them together, with the hope of increasing the population. Only Bucky’s not interested in being someone’s omega. Not until he meets Steve. But Steve’s not one of the alphas in the program. He’s his bodyguard.

Summary: Or the one where Clint Barton has never met Bucky Barnes before in his life, and if he says it enough maybe everyone else will believe him.
while we pretend to sleep (ao3) - Typo66
steve/tony
E, 52k
Summary: Tony pretends to be an alpha. Then he forgets he had been pretending. One thing he remembers is Steve. Steve tries to help out in his old fashioned, ethically strict way. Tony likes making big gestures. He has never been subtle.
